This week on Clean Power Hour Live, Tim Montague and John Weaver break down the biggest solar and storage headlines shaping the industry right now.

The US reached 40 gigawatts of grid storage in 2025, beating the 35 gigawatt goal set in 2017. But supply chains are struggling to keep up. 100 amp-hour battery cells are sold out through 2026 as demand surges across residential, commercial, and utility projects.

John discusses his company's expansion into Illinois, where new legislation adds 873 megawatts of solar and 3 gigawatts of storage over the next few years. The state is also unlocking VPP programs, giving distributed batteries a bigger role in grid operations.

Episode Highlights:

• Illinois passes new legislation adding 873 megawatts of solar and 3 gigawatts of storage, enabling VPP programs 
• Battery cell shortage intensifies as 100 amp hour cells sell out through 2026 due to demand across residential and utility sectors (PV Magazine)
• Electric freight vehicles and delivery trucks show explosive growth in China, with EVs approaching 50% of all vehicle sales (John Hanger via Blue Sky)
• Natural gas prices spike above $5, expected to drive electricity rate increases in 2026 through utility cost recapture mechanisms (Bloomberg)
• US extends tariff exclusions for solar manufacturing equipment, including silicon growth furnaces and wire saws (PV Magazine)

The discussion explores why battery adoption creates a flywheel effect for solar installations, how state incentives are driving developer interest, and what supply chain pressures mean for project timelines in 2026.
